It seems as if pace of play is being talked about almost every week on the PGA Tour - and that was again the case at Riviera on Sunday.
Kevin Na has been criticised many times before for this reason, and is considered by many to be one of the, if not the slowest player on tour.
And this was showcased again on Sunday, as many viewers heckled him for taking way too long over a number of his strokes.
At the forefront of their outrage was Na's antics before his par putt on just his second hole.
With his ball three feet away from the cup, it seemed a formality that Na would simply tap the ball in and move on to the next hole.
However, the American took roughly one minute and 20 seconds in lining up his putt and taking practice strokes, before he finally rolled it into the middle of the cup.
KEVIN PIETERSEN WAS NOT IMPRESSED
Na was enduring the wrath of all corners on Twitter, but arguably none were more enraged than English cricketer, Kevin Pietersen.
Pietersen, who is an avid golf fan and possesses a handicap in the single digits, posted a video of him reacting to Na taking an age on his short-range putt on the second.
PIETERSEN HAS NOW SHOWN NA HOW IT'S DONE
And it seems Pietersen is still reeling from Na's antics, having since posted a follow up tweet directed at the one-time PGA Tour winner.
Taken at Trump International Golf Club in Dubai, the 37-year-old again reiterates just how long the American took on his tap in, before saying to Na: 'This is what you do with a tap in mate'.
Pietersen then turns way from the camera and begins counting, before nudging his ball into the hole after just seven seconds.
The cricketer then turns back to the camera before finishing the video off by saying: 'That's how it's done bro.'
Although Na was under a lot more pressure to sink his putt than Pietersen was in, he should look at this video and realise that he does need to speed up his play; for the good of the sport.
